Goodbye AC: This New Roofing Material Keeps Houses Cool
3rd October 2021
A scientist has invented a material that reflects the sun’s rays off rooftops, and even absorbs heat from homes and buildings and radiates it away. And — get this — it is made from recyclable paper.
…
Yi Zheng, an associate professor of mechanical and industrial engineering at Northeastern University, calls his material “cooling paper.”
He hopes that people everywhere will wrap their houses in the cooling paper one day, reports Good News Network. In addition to the cooling benefits, the paper doesn’t require any electricity, and it is 100% recyclable.
The paper can reduce a room’s temperature by up to 10 degrees Fahrenheit, making it a radical but effective alternative to today’s air conditioners, which consume a lot of power.
Ten degrees doesn’t help much with a Texas summer. Perhaps this will be useful in Florida or California.
